-MACH|NE FOR CUTTING LOAF-SUGAR.

Specification forming part of Letters Patent No. 14,490, dated March 25,1856.

To all whom it may concern.-

Be it known that we, ADoLPH BROWN and FELIX BROWN, of New York, in thecounty and State of New York, have invented a new and useful Machine forCutting up Refined Loaf-Sugar into Regular Pieces; and we do herebydeclare that the following is a full and exact description of the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

The nature of our invention consists in cutting up refined sugar intoregular and equal morsels in such a manner that the appearance of thecrystals on the outside shall be as much as possible preserved. For thatpurpose we cut the loaf or lump sugar first into slices or slabs of therequired thickness by means of straight or circular saws, then passingsaid slabs between rollers having brushes around their circumference forthe purpose of cleaning off the dust produced by the process of sawing,thereby reproducing the appearance of the crystals on the outside, and,lastly, passing the such-cleaned slabs between rollers having steelknives around their circumferences, corresponding to each other andacting on both sides of the slabs simultaneousl y like pinchcrs, bywhich action said slabs are cut into cubical morsels of the requiredsize.

In the accompanying drawings, Figure I represents a top view, and Fig.II a side view of the machine.

The sugar, after having first been cut in slabs of the requiredthickness by straight or circular saws or by any other similarcontrivance, is put into the hopper A. In the sides of this hopper Aopenings are cut, covered with wire, so that the brushes a a, fastenedto the periphery of the drums B B, can reach into the hopper so as toclean the slabs of sugar, as they pass down the hopper, from the dustadhering to the same from the process of being cut into slabs. By thisprocess of cleaning or brushing off the sawdust the crystals arereproduced on both sides of the slabs. The drums B B run in bearings inthe frame M, and are each provided with two pulleys, mp and m p,fast totheir shafts, respectively. The slabs of sugar which have by theabove-described process acquired again their crystal appearance on thesides fall upon the endless band E, running over the rollers S and Z,vand are carried by the same into the second hopper, D, situated aboveand between the cutting-rollers F F, to be cut up into cubical pieces.These cutting-rollers F F consist of drums made of wood or iron, runningin bearings fastened to the frame M. In the circumference of these drumssteel plates or knives or are let in parallel to each other and the samedistance apart as the thickness of the slabs of sugar. These plates orknives n have recesses or notches corresponding with each other, intowhich the cross-knives o are fitted, running parallel to the axes of thedrums and to each other, and forming, with the knives n, squares equalto the thickness of the slabs. These knives 0 are screwed to the drums,and hold thereby at the same time the other knives, a, in their places.

H H are teeth-wheels fast 011 the shafts of I the rollers F F, toconnect both rollers together.

L L are fast and loose pulleys on the shaft of the roller F, to applypower to the same.

M is the frame of the machine. Motion being given to theroller F, thesame will be communicated through the gearing H and H to the roller F,and through the band G, passing over the shaft of the drum F and thepulley p to the drum B. The drums B and B are connected together by theband K, passing over the pulleys m and m, and the band N, passing overthe pulley p, and the pulley 20, fast to the end of the roller S,communicates motion to the endlessband E.

What we claim as our invention, and desire" to secure by Letters Patent,is-

1. The application and use of two or more rollers having brushes aroundtheir circumferences and acting upon both sides of slabs of sugar, forthe purpose of cleaning off the dust adhering to. the same by theprocess of sawing, thereby reproducing the appearance of the crystals,as described.

2. The application of drums or rollers'connected together by gearing,having steel knives inserted and attached around their circumferences,forming squares and corresponding to each other, and acting on bothsides of sugar slabs simultaneously, like pinchcrs, for the purpose ofcutting up said slabs into regular cubical morsels, in the mannerspecified.
